Read like this: "(A private method) and (all methods declared=20
immediately within a final class (=A78.1.1.2)) behave as if they are=20
final, since it is impossible to override them."  In other words

P"final"(m) OR P"declared immediately within a final class"(m) =3D>=20
P"behaves as if final"(m).

But you can never invoke A.init() from methods in B or descendants.=20
A.init() is final because it can only ever be seen in A.
